300

How many parents are required for asexual reproduction?

ONE

300

Why can large populations from asexual reproduction be a disadvantage?

Creates food scarcity and competition

300

What type of asexual reproduction occurs when an organism splits into two identical cells?

Fission or binary fission

300

How do environmental factors affect asexual reproduction? 

They create variation

300

An organism that has 2 identical alleles for a trait.

Homozygous or purebred

This type of letter is used to represent a recessive gene.
Lower case letters

A hybrid brown-eyed man is crossed with a pure recessive blue-eyed woman. What percent of their offspring will have brown eyes?
50% will have brown eyes
400
This type of letter is used to represent a dominant gene.
Capital letters
400
2 hybrid brown-haired people are crossed. What percent of their offspring will have pure dominant traits?
25% will be pure dominant
400
A homozygous recessive white haired rabbit is crossed with a homozygous dominant brown haired rabbit. What genotype will all the offspring have? Use B/b for alleles.
All offspring will be "Bb".
500

How do offspring compare genetically to their parent in asexual reproduction?

They are genetically identical

500

How do plants reproduce through vegetative reproduction?

They grow new plants, using runners, bulbs, tubers, or plantlets.

500

Which method of asexual reproduction allows plants to spread rapidly through underground stems?

Rhizomes or runners (Vegetative Propogation)

500

What is an advantage of sexual reproduction?

Diversity or variation of traits

500

2 heterozygous brown-eyed people are crossed. What are the possible genotypes and phenotypes of their offspring? Use B/b for alleles. (Brown eyes are dominant and Blue eyes are recessive)

Genotypes: 1 BB, 1 bb, 2 Bb Phenotypes: 3 brown eye, 1 blue eye
